ESCUTCHEON-PLATE AND LOCKFOR TELEPHONES.

SPECIFICATION formingpart. of Letters Patent No. 772,986, dated October 25, 1904. Application filed August 25, 1903., Serial No. 170,707. (No model.)

I To ali'whom, it may concern:

Be it known that I, KLAs WEMAN, a subject of the King of Sweden andNorway, and a resident of the city, county, and State of New York, have invented a new Combined Escutcheon-Plate and Lock for Telephones, of which the following is a specification.

My invention refers to combined escutcheonplates and locks on telephones, and is particularly applicable to what is known as walltelephones.

The object of my invention is to construct an escutcheon-plate which will at the same time serve as a lock, operating automatically without the aid of a key, the possibility of losing the key.

Previous to my invention it has beencustomary to use locking devices which require a key or necessitate the withdrawing'of one or more screws before the door or. lid can be opened. The'key is often lost, and the undoing and tightening of screws take unnecessary time. Where my invention is applied, no key is needed, and the door or lid may be automatically closed and locked. The simple means by which thisresult is attained are fully described and explained in this specification and illustrated by the attached drawings, forming part thereof. 1

Like letters of reference designate like parts on the drawings.

Figure 1 represents a front elevation of my invention; Fig. 2, a top View thereof. Fig. 3 shows the invention applied on the telephonebox, the door being open; and Fig. 4 is a View showing details.

Referring to the drawings, the letter A designates the larger plate, intended to be. fastened on the stationary part of the telephone by means of screws or the like entering the holes f, g, and it. This plate is recessed atm in order to permit the movement of the telephone switch-hook.

B is the smaller plate of the locking device and is secured to the movable part of the telephone. The plate B is angular in shape and is secured byscrews or the like to the inner side ofdoor or lid 0. I

C, Fig. 2, is a knob or projection attached and thus prevent shown in the drawings,

4. The spring D is slightly bent in order to make its operation more effective. When the pieces are mounted on a telephone-box, as illustrated by Fig. 3, and thedoorOis closed,

the knob 0, having its outer edge rounded off, will slide along the back surface of the plate A till it reaches the hole E, which it will enter and will then be forced through said hole E by the pressure of the spring D.

The inner edge of the knob C is full and sharp.

The pressure of the spring D will prevent the knobO from slipping out of the hole E when force is applied to open the door unless atv the same time the knob Cis pressed inward, in which case the edge of the knob C will pass the inner edge of the plate A, thereby releasing the door 0.

It is obvious that the appliance may be changed to suit different types of telephones where the opening of a door or lid is desirable. It is also obvious that the knob C may be made square or oblong and the hole E of a similar shape.-

I do not wish to be limited to the details as these may be modified in several particulars without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is 1. In combination,in a combined escutcheon plate and lockfor telephones, idly attached to the telephone-box adjacent one edge thereof, and having opening through its body to one side of the recess, a second member of angular shape in cross-section having one part secured to the under side of the movable section or cover of said box, and its other part designed to abut against the edge of the first member, and an angular resilient arm having one part secured to the first part of the second member and having further a freeend carrying a knob to engage the wall of the opening in the first a member rig a recess in one edge to accommodate the switch-hook, and an member, said arm being entirely hidden bel and a knob at the free end of the arm engaghind said two members When the cover is ing the wall of the opening in said plate, said closed, substantially as described. arm being entirely hidden when the cover is 2.
